NOT E: N/O (normally open) and N/C (norm ally closed)
refer to
contact status in standby mode. On a two-alarm system, a
high-level alarm condition on any sensor will override a low-
level alarm condition on another sensor.

relay may be set for normal or Fail-Safe operation by setting
jumper JP1 on the cont rol unit’s printed circuit board.
4.4. Power Connection

120V systems. Connect the m ain power s upply t o terminal block CN3
(on 1 & 2 channel systems), or fused t erminal block mounted on base of
control unit (4 - 6 channel systems). Ensure that ground connections to
the lid and base of the enclosure are maintained.
NOT E: Connection to the main power supply must be made
via an approved, readily-accessible, switched and fused plug
and socket (or as per local wiring regulations) which should be
within 10 feet (3 meters) of the cont rol unit.
